CHARLES T. KEMMER, OF CLEVELAND, OHIO.

METHOD OF PREPARING SURFACES FOR THE FORMATION OF DECORATED REMOVABLE FILMS.

SPECIFICATION forming part of Letters Patent No. 437,305, dated September 30, 1890.

Application filed February 24, 1888. Serial No. 265,143. (No model.)

To all whom it may concern:

Be it known that I, CHARLES '1. KEMMER, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a Method of Preparing Plaster-ed or other Hard Surfaces to Form and Decorate thereon Removable Films of Paint, of which the following is a specification.

The nature of my invention consists in pre paring plastered or other hard surfaces in such manner as to enable the removal of the films of paint which have been put thereon for the purpose of being frescoed or having other decorations executed thereon.

The object of this invention relates to the mode or means by which these decorations are arranged in their artistic position, allowing the removal of said decorated films without any preparatory manipulations, such as are necessary by the means heretofore employed for the above-said purpose.

For ceiling decorations the ceiling of the artists studio may be advantageously pre pared, and for wall decorations the walls of the studio may be used for the same purpose.

Heretofore either textile fabrics or paper were employed to produce removable films of paint thereon, said fabrics or paper having to be moistened, or rendered wet, for the purpose of dissolving the intermediate size before the decorated films could be removed.

I prepare the surfaces upon which the said removable films of paint are to be produced in the following manner: First, a size of glue is applied over the entire surface, to form an adhesive basis for a coat of oil-paint, which is put on over the said glue size. The paint after being rubbed down receives a coat of varnish, which virtually finishes the preparation of said hard surfaces. As an intermediate size upon this surface, over which the films of paint are applied, a covering of gelatinous moss and glycerine is put on in two or more coats. When the last-named coats are dry, then the oleaginous coating may be put on to form the films of paint. The cohesive qualities of the coating of said size are comparatively slight; but as applied upon a smoothed surface, as before stated, they become sufficiently efficient for the purpose intended, but allowing an easy separation or removal of the paint film from its temporary position by simply peeling or pulling said paint film from the said sized surface. Large films of paint, however, are first cut into strips of suitable width and length before they are withdrawn from said surfaces, to facilitate removal, transportation, and application of said films.

These decorated films of paint are applied to interior house decoration, &c., and form a substitute for frescoes or oil painting executed directly upon the walls or ceiling.

What I claim as my invention, and desire to secure by Letters Patent, is

The herein-described method of preparing surfaces for the formation of decorated removable films, consisting in first applying to said surface a size of glue, then painting this surface, applying to the surface thus prepared an intermediate size consisting of gelatinous moss and glycerine, and in forming upon this surface the decorated films, substantially as described.
